A Bank in Every Pocket

2007 CE

History · Contemporary · Holocene · Meghalayan

In 2007, the year the modern smartphone was unveiled in California, a plainer revolution began in Kenya: M-PESA, money stored on a phone and sent by text. It reached most Kenyan households within a decade, and its effects were measured rather than assumed: higher consumption, an estimated two percent of households lifted out of poverty, women moving out of farm work and into business. Across much of the developing world, the phone rather than the bank branch became the way into the financial system.

Why it matters

By the 2010s, more people had access to a mobile phone than to a toilet: the fastest spread of any technology in our history, and one of the most evenly shared. Mobile money shows what that reach does when it meets a real constraint: no safe way to save, to send, to borrow. It leapfrogged a century of banking infrastructure in ten years. The next billion people to come online will meet the world's knowledge, markets and manipulations through a device in their palm.

Dating & uncertainty

M-PESA launched in Kenya in 2007, letting value move by text message; within a decade it had been adopted by the vast majority of Kenyan households. The measured effects give the anchor its weight: access to mobile money raised per capita consumption and lifted an estimated 2 percent of Kenyan households out of poverty, the gains more pronounced for households headed by women.
